[anchenqlw]

Cookbook contribution

Summary

• Content type: Showcase
• Locale: zh-CN
• Demo source included: no
• Target audience: Product managers, Agent developers, and technical leads building long-running Agent applications and governed software self-evolution workflows
• User problem and expected outcome: Show how LittleMemeWorld uses Qoder Cloud Agents both as the core application foundation for persistent Cat Agents and as the execution foundation for a fully implemented, governed software self-evolution pipeline. Readers should understand how the product's life loop and evolution loop share one QCA foundation while keeping identities, permissions, and authoritative facts separate.
